I found some ridiculous stuff on SmartMusic by this guy, he writes some tough music! One in particular was Attack of the Killer Tomatoes. If you haven't heard this, you should definitely check it out. It's fast too, I think 240ish is the fast tempo and 210 is the slow. Here's a link to most of the song: YouTube - Attack Of The KIller Tomatoes-Gordon Goodwin's Big Phat Band Has anyone played any pieces, whether they be jazz or not, harder than this? I consider myself a decent player, but I just could not play this piece.
